Why should that be advertising? He is asking others about their experiences with this shop
Because it is very likely that this user is advertising for this site. He has only just registered in the forum today. The site is Polish-owned. He has a Polish username. He greets from Berlin. The company is also in Berlin. Why doesn’t he just go there and see how reputable they are? The gentleman could at least spend 3€ and pay the forum for an advertisement.
In our forums, we consistently warn against this with a cost note. By registering, the user agrees to refrain from advertising posts. It has always worked so far and brings in a few thousand euros into the budget annually I can only recommend it..
